What is the loudest electronic siren?

[ver tum]

Just curious. Does anyone know what the loudest electronic siren is, and what it's DB rating is?

[jkvernon]

Currently the loudest electronic siren is the Whelen WPS-4004 and Vortex R-4. The loudest ever made would likely be the Whelen WPS-4008.

Some will argue that the loudest electronis siren ever made was the EOWS 812 with a 132db output at 100ft., but the catalog that that came from had a bunch of other screwed up output ratings like 128dB for a TBeam and 131dB for a TBolt.

What are the real DB ratings for those Whelens, and for the EOWS812?

Didn't Federal Signal actually release a Series C Thunderbolt that was capable of 131dB output at 100' in an attempt to compete against other sirens?

Also, what does a Whelen WPS 4008 look like?

Yes Ver Tum those are the real Db ratings on the wonderful 812.

The 4008 is basically a 4000 series siren with 8 horns instead of 4, and with a humongous " [ " on the back of it for stability.

[AllSafe]

No, there was a different reasoning behind the big fin on the back. I forget what, but it has been mentioned here.

[SirenMadness]

The fin on the back was to reduce stress on the rotational mechanism on the siren.

[MattDean1003]

'Twas not a fin, peeps, 'twas a bracket to kinda hold everything together.

No it was to protect the belt drive rotational system on early VortexR sirens. The VortexR-4 and WPS 4004 are both rated at 129dB.
